. Application filed November 22, 1913. Serial No. 802,339.

To all whom it may concern Be it known that I, CLARENCE -W. W'rrrrn,

dent of North Bennington, in the county of Bennington and State ofVermont, have invented certain new and useful Improvements inReflectors, of which the following is a specification.

This invention relates to reflectors, more particularly to reflectorsfor use with incandescent lamps, and the objects of the invention are toconstruct a reflector that is very strong and durable.

Further objects of the invention are to provide a guard for the open endof therefiector that can be locked into position to prevent breaking orstealing of the lamp.

To. the accomplishment of the above objects and to such others as mayhereinafter appear the invention comprises a reflector, having at itsopen end an outwardly extending shoulder at right angles to a downwardlyextending flange having a beaded edge, and means for holding the outeredge of a guard in position against said shoulder.

The invention also comprises means for removably locking the guard inthe-open end of the reflector.

Referring to the drawings: Figure 1 is a side elevation of a reflectormade in accordance with the invention secured to an ordinaryincandescent lamp socket. Fig. 2 is a bottom view of Fig.1. Fig. 3 is aView showing the reflector section. Figs. l and 5 are detail views ofthe locking means for the guard.

In the drawing A designates an ordinary electric light socket having acircular rib B which is adapted to engage a corresponding groove orrecess C provided in a split ring D which is made of metal and adaptedto be sprung into position on the socket A as clearly shown in Figs. 1and 3. The lower portion of the split ring D is threaded and adapjted toengage a similarly threaded collar secured to the top of the reflectorF.

When the lamp Gr is screwed into position it will be seen that the.reflector cannot be removed from the socket without first removing thelamp, as the glass globe of the lamp is larger than the opening in thetop of the reflector.

The reflector .F is preferably made of aluminum, although if desired thesame can be made of any other suitable metal, that v P which is can bespun into shape and formed at its open end with an outwardly extendingshoulder H at right angles to a downwardly extending flange J, having abeaded or rolled edge K. This shaping of the open end of the reflectorby providing a shoulder having a beaded flange greatly strengthens thereflector, which is very desirable as reflectors of this type are put tovery rough usage, and it is important that the reflector retain itsoriginal shape to properly reflect the light.

The present method of shaping the open end of the reflector permits of asuitable guard or covering M being secured in the offset portion of theend of the reflector so as not to interfere with the proper reflectingqualities of the reflector. In the drawing the guard or covering M isshown as a wire screen of very large mesh, the edges of which aresecured to a large wire ring N which fits in the oflset portion of thereflector as clearly shown in the drawings. This guard or covering Mprevents breaking of the lamp G and when the guard M is locked inposition in the end of thereflector also prevents the lamp being stolen,as the lamp cannot be removed without first removing the guard. In thepresent instance the guard is secured in position by means of twoprojections or pins 0 secured to the flange J and also by means of amovable pin P secured to a flat spring Q, as clearly shown in Fig. 4. Inthe present instance the locking of the guard Min the endof thereflector is accomplished by'locking the pin provided with a slot It inwhich the bolt S of the lock T is adapted to en gage as clearly shown inFigs. 1! and 5. In-

stead of providing a wire guard such as described for closing the end ofthe reflector, a piece of glass which may be colored, when the same isto be used for photographic purposes, can be used and held or locked in1 position in the same manner. The 'oif-s'et portion of the end of thereflector makes" a light tight joint and when a red piece of glass isused for photographic purposes no white light will pass around the edgeof the glass which is a very important feature of this construction. I

While the invention has been described with particular reference to thedetails of construction, the same'is not to he ccn'sid ered as limitedthereto, as many changes g amass? can he made and still fall within thescope of the invention setjfiorth in the following claims.

What I claim is? v 1. A reflector comprising'in combination a guard, theopen end of the reflector haying ail-outwardly er ztending shoulder atright angles to a downwardly extending flange, and means for remo'yahlyholding the outer edge of said guardian position against said shoulder,said shoulder and said flange being arranged out ,ef the path of thelight reflected by said reflector.

v 2. A reflector comprising in combination a guard, the open end of thereflector havii'ig an outwardly extending shoulder at right ones-Enos W.WHITE.
